Power Plant Analysis and Evaluation of occupational hazards


BA, deputy director of the physician. 1.2.1 Determination of the project health based on a preliminary investigation of the plant work, select test items are: dust, noise and carbon monoxide, sulfur dioxide, nitrogen dioxide, nitric oxide, manganese dioxide, hydrochloric acid, sulfuric acid, sodium hydroxide, ammonia, hydrazine, hydrogen sulfide, methane and other toxic substances l2. The determination of the hot season has passed, the high temperature as a key evaluation factor. 1.2.2 the choice of sampling points according to the site investigation, according to monitoring points,[link widoczny dla zalogowanych], the noise monitoring points located 141. 1.2.3 Detection based on the detection of toxic substances based on the 2B dust measurement using the FC-type dust sampler for a sampling. Click Noise intensity measured in accordance with the 2 Results 2.1 Determination of the boiler manufacturing plant Pi toxic, chemical water treatment system 2 Liuya Jing, et al. Occupational Hazards of a Power Plant Analysis and Evaluation of dosing between 143 pH, ammonia and hydrazine dosing device, battery room, sewage treatment systems and boiler maintenance site of acid, alkali, ammonia, hydrazine, etc. A total of 12 testing of toxic substances, only the manganese dioxide exceeded the standard, and other toxic substances are in line with The results in Table 1. Wrapped in a toxic substances in workplace air test results (mg / m) testing project monitoring sites to monitor the concentration range of health limit points pass rate (%) 2.2 Determination of dust content of free silica dust were measured, including ash Field and ash content of free silica dust in the library 10% a 50%; total of 26 posts Test Dust, a pass rate of 80.8%, the results shown in Table 2, Table 3. Bad 2 free silica dust in the determination of free silica content of the results of test sites (%) 3-like 2 ASH belt furnace slag drum platform 3 Ash ash ash bucket platform Room 4tB belt drive electrostatic precipitator sleep 3 between dust concentration in workplace air test results (mg / m) 2.3 Noise monitoring results in accordance with the air compressor room, Fan room, steam room and other noise in the workplace were measured. Noise detection in 141 points, 10 points, occupation of other operating point determination results are in line with My voice wrapped 4 Monitoring Results workplace discussions that sold 3 the results of the monitoring, the plant exceeded the positions of gray dust, ash discharge database,[link widoczny dla zalogowanych], transport ash, ash yard rolling, boiler maintenance insulation workers, welders, due to the above post jobs for a long time put gray device is not closed, operation of secondary dust ash and ash-field situation is more serious when the space is small and the repair job poor ventilation, resulting in excessive welding fumes and manganese dioxide. Excessive noise for the 3,4 positions of a furnace fan, coal handling system, coal crusher lounge, library gasification ash fan room, steam room 1 of a steam pump and steam turbine 4 0 m 2,[link widoczny dla zalogowanych],4 the vacuum pump. The reason for addition to the noise emission values ​​of the equipment itself higher, another main reason for the boiler room of a zero-meter blower fan and centralized allocation, there is noise superimposed. The plant have a sound occupational health and management of labor organizations and management systems, occupational health care establishment of a working file. Occupational diseases has not been found. Work in the prevention of occupational diseases, the plant effective measures, dust,[link widoczny dla zalogowanych], drugs,[link widoczny dla zalogowanych], noise facilities, the overall evaluation results meet national health standards, but in some posts are still excessive dust and noise pollution situation, still need to strengthen governance. The plant should fundamentally strengthen the protective measures of occupational diseases, occupational hazards so that the concentration (intensity) control in the national health standard limits the following, and should enhance personal protection, occupational health training and other measures to establish a sound working environment monitoring of occupational hazards, Strengthening occupational health supervision and management.
